Aerial refueling demonstration at Wright Air Development Center in Ohio, United States. View of a B-50 bomber, flying in trail behind KC-97 tanker aircraft, as the B-50 maneuvers for in-flight refueling. View of pilot in cockpit of the B-50. View from the B-50 cockpit as the refueling boom nozzle extends toward it from the KC-97. This is followed by an immediate view of the event, from the tail of the KC-97, as the nozzle connects with a single point refueling port on the top of the B-50. Aerial view from another airplane, of the two aircraft flying during the fuel transfer operation. (Light panels, appearing from this side view, as bumps on the underside of the KC-97, are designed to help a pilot attain and hold the proper position beneath the tanker during refueling.)
